There is no code in OpsCenter that ever clears or deletes events, so I would be very surprised if that happened during the upgrade. The only way that could happen is if you previously truncated the OpsCenter keyspace, or it didn't exist on the cluster and had to be created when opscenterd started up.
</p></blockquote>
<p>I did not truncate data and did have some events before updating. Did the structure of this data change, possibly making old data unreadable ? Did it happened to more users ? But once again this is not a big deal for me, just trying to help.</p>
<blockquote><p>
Added support for CQL3 column families (limited Data Explorer support)
</p></blockquote>
<p>I saw this but did not knew the exact limitations. I get it better now.

<blockquote><p>What about this part of Yue Zhang message</p></blockquote>
<p>We explicitly mention that the Data Explorer support for CQL3 column families is limited. Specifically, it will only work if the column family was created with the COMPACT STORAGE option. If it was not, you will see the "not currently supported" message.

Thu, 01 Aug 2013 02:46:39 +0000Alain14294@http://www.datastax.com/support-forums/<p>Hi, I do not have the 'slice of null' bug today anymore. But you must be right I only have a few events like opscenter starting up / shutting down since I restarted it this morning. My cluster is running for 2 years now... It looks like the upgrade removed all events, this is not a big deal for us but is this the expected behavior ?</p>
<p>If I can help you somehow about this point just let me know.</p>
<p>What about this part of Yue Zhang message :</p>
<blockquote><p>
From OpsCenter 3.2 release note(http://www.datastax.com/docs/opscenter/release_notes#opscenter-3-2), it tell me “Added support for CQL3 column families (limited Data Explorer support).”，but it not works.</p>
<p>The message below:</p>
<p>Viewing data in column families created with CQL3 is not currently supported. We recommend using one of the DataStax drivers or cqlsh as an alternative.</p>

Wed, 31 Jul 2013 10:07:48 +0000mbulman14236@http://www.datastax.com/support-forums/<blockquote><p>“Error saving column family: required argument is not a float”</p></blockquote>
<p>This is a known issue that will be fixed in the next patch release of OpsCenter (3.2.1), which will be available soon.</p>
<blockquote><p>Error loading events: Cannot call method 'slice' of null</p></blockquote>
<p>It looks like this would occur if there were no events in the OpsCenter.events column family, which is not a normal case. If you refresh the UI does it still occur? I will file a ticket to get that error resolved, but it seems like there is a bigger underlying issue.
